Question

If rice requires 10 cm depth of water at an average interval of about 10 days and if the crop period of rice is 120 days, the delta for rice is:

• A. 10 cm
• B. 12 cm
• C. 100 cm
• D. 120 cm

Hint:

Delta (\(\Delta\)) is calculated by multiplying the irrigation depth by the number of irrigations.

Answer 1

The Correct Option is D

Step 1: Understanding Delta
Delta (\(\Delta\)) is the total depth of water required by a crop during its entire growing period: \[ \Delta = \text{Water applied per irrigation} \times \frac{\text{Total Crop Period}}{\text{Irrigation Interval}} \]
Step 2: Substituting Values
\[ \Delta = 10 \times \frac{120}{10} = 120 \text{ cm} \]
